EXTENSION-LADDER AND WINDOW-JACK.

SPECIFICATION forming part of Letters Patent No. 575,574, dated January19, 1897. Application filed April 1, 1896. Serial No. 585,739. (Nomodel.)

To all whom it ntay concern:

Be it known that I, JOHN MARTIN PUGH, of Reno, in the county of Washoeand State of Nevada, have invented a-new and Improved Extension-Ladderand Window-Jack, of which the followingis a full, clear, and exactdescription.

The object of the invention is to provide a new and improved combinationextensionladder and window-jack which is simple and durable inconstruction and arranged for conveniently changing the device from anordinary step-ladder to an extension-ladder or a Window-jack.

The invention consists principally of a ladder formed by a bottomsection and a bracesection, the sect-ions being pivotally connected witheach other to permit of placing the sections at angles to one anotherfor an ordinary step-ladder or for a window-jack, or to bring thesections in alinement to form an extension-ladder, the bottom sectionbeing provided with blocks for receiving the projecting ends of thebrace-section.

The invention also consists of certain parts and details andcombinations of the same, as will be fully described hereinafter andthen pointed out in the claims.

Reference is to be had to' the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the improvement arranged as an ordinarystep-ladder. Fig. 2 is a similar view of the same as arranged as awindow-jack and applied to a window, with part of the building insection. Fig. 3 is a perspective view of the improvement arranged as anextension-ladder, and Fig. 4 is an enlarged front elevation of the upperstep of the bottom section.

The improved ladder and window-jack is provided with a step-ladderformed by a bottom section A, on the upper end of which is pivoted at Ba brace-section 0, having its side pieces 0 projecting beyond thepivoted end B, with the free ends of said projecting ends beveled, as atC to engage and abut on blocks D, rigidly secured to the outer faces ofthe side pieces A for the bottom section A. Thus when the brace-sectionO is moved in alinement with the bottom section A,as shown in Fig. 3,then the projecting ends of the side pieces 0 abut and rest on theblocks D to hold the two sections in alinement when the ladder isresting against the side of the building or other place. Both sections Aand O are provided with steps for a'person to readily ascend anddescend.

On the blocks D are pivoted connectingbraces E, preferably made of metaland formed with notches, one of which is adapted to engage a pin F,secured in a guideway G, secured to the sides 0 of the brace-section C.By this arrangement the two sections A and 0, when placed at angles toone another for use as an ordinary step-ladder or windowjack, are held asuitable distance apart, as will be readily understood by reference toFigs. 1 and 2.

On the side pieces A of the section A and near the lower ends thereofare secured notched shoes H, adapted to engage the window-sill I, asillustrated in Fig. 2, to hold the section A in a horizontal positionand extending out of the window, with the other section 0 abutting withthe free ends of its side pieces 0 011 the outside of the wall of thebuilding. When the device is in this position, it is necessary toprovide a suitable floor on the top of the section A for a person tostand on, and this floor is formed by the upper step J of the section A.The upper step J is made in two pieces J J hinged together at J 3 attheir rear ends, so that one folds on the top of the other, as isplainly illustrated in Figs. 1, 3, and 4.

The forward end of the piece J 2 is pivotally connected by links J withtransversely-extending braces K, on which is adapted to rest the step Jwhen the device is used as an ordinary step-ladder or as anextension-ladder. When the step J is to be used as a floor, then thesaid step is swung forward on the links J and the top piece J is foldedfrom the bottom piece J so that the two pieces are in alinement with oneanother and rest on the side pieces A of the bottom section A to formthe floor for a person to stand on, as will be readily understood byreference to Fig. 2.

hen the device is used as a window-jack, then the arms E securely holdthe brace-section A in place to insure a proper support of the sectionA. When the device is used as an extension step-ladder, the pivotedarmsE are not used, as the top sect-ion is securely held in place by theblocks D.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. A device of the class described, comprisinga ladder consisting of a bottom section provided with a platform and abrace-section, the sections being pivotally connected with each other topermit of placing the sections at angles to one another for an ordinarystepladder or for a window-jack, or to bring the sections in alinementto form an extensionladder,the brace-section h avingits side pieceslocated at the outer faces of the side pieces of the bottom section, theside pieces of the brace-section projecting beyond the pivot point andbeveled at their ends, and blocks on the outer faces of the side piecesof the bottom section, the said blocks having their upper faces beveledto engage the beveled ends of the brace-section ,whereby the sectionsare held in alinement, substantially as shown and described.

2. A device of the class described, provided with a ladder-sectionhaving shoes for engagement with the window-sill, and a top step made intwo pieces hinged together at their rear ends and adapted to fold one ontop of the other, the forward end of one of the said pieces beingconnected by links with the sides of the section, whereby the piecesforming the step can be swung forward torest on the side pieces of thesection to form a floor or platform, substan tially as shown anddescribed.

3. A device of the class described, comprising a ladder made in sectionspivotally connected witheach other,connectin g-braces pivoted on onesection and adapted to engage pins on the other section, shoes held onone of the sections and adapted to engage the window-sill, and a floorfor the section carrying the shoes and formed of two pieces pivotallyconnected with each other and connected by links with the sides of saidsection, substantially as shown and described.

4. A device of the class described, comprising a ladder made in sectionspivotally connected with each other,connecting-braces pivoted on onesection and adapted to engage pins on the other sect-ion, shoes held onone of the sections and adapted to engage the window-sill, a floor forthe section carrying the shoes and formed of tWo pieces pivotallyconnected with each other and connected by links with the sides of saidsection, and brackets held on said section and adapted to form a restfor said pieces, substantially as shown and described.
